To tested if the adding of consolidative SBRT to TKI in EGFR mutated patients with less than or equal to 5 metastatic sites (primary + 5) will improve progression free survival (PFS) compared to TKI alone.
Name: Radiation: SBRT
Description: A first line TKI (Gefitinib 250mg po qd or Tarceva 150mg po qd ) will be administered according to the standard dosing of the drug for metastatic NSCL during a 1-week run-in period after which SBRT will be delivered to the all oligometastatic lesions concurrently with the TKI. The SBRT dose will be , ranging from at 25Gy (5 Gy per fraction) to 40 Gy (8 Gy per fraction).Type: RadiationTKI with SBRT
Name: TKI (Gefitinib or Tarceva )
Description: A first line TKI (Gefitinib 250mg po qd or Tarceva 150mg po qd ) will be administered according to the standard dosing of the drug for metastatic NSCL, no local therapy apply to oligo-metastatic sites.Type: DrugTKI without SBRT TKI with SBRT
Description: Evaluate the effect of TKI with or without SBRT on progression free survival
Measure: Progression free survival Time: 4 yearsDescription: To describe local control and out-of-field disease progression
Measure: local control Time: 4 yearsDescription: To evaluate overall survival after SBRT followed by maintenance chemotherapy in comparison to maintenance chemotherapy alone.
Measure: Overall survival Time: 4 yearsAllocation: Randomized
